Callisto, I actually have the 2-3 flare and hard 3 hit since my 23 was new. Dealership blew me off at the time, don't remember what they said. And I did a pan drop, clean out, and new filter/fluid at 5K miles. It made no difference in the 2-3 issue. I have done the relearn a couple of times per your video with no noticeable changes. I'm actually not worried about the shift issue since I'm aware of it and drive very gently for 3-4 miles until it shifts normally. No biggie for me to do. But it would be nice to get it resolved. I hope the reprogramming doesn't cause something else to act up. haha Please tell me more about what information you request that I ask for when I get this done? Thanks for your interest and help. Tom

 

Sounds good Tom!
I think I read that but I read so many threads and responses on this and few other forums every day I can't remember all of them and the information on them.
If after the visit to Mazda should the problem, continue shoot me a PM I may have a couple things you can try as well.

 

Thank you so much for posting this jg5000. I had taken my 2022 CX-5 2.5L in a couple times for the harsh 2-3 shift when cold. Like others it was only the first shift and happened if I let it warm up 1 minute or 5 minutes. It doesn't matter if it is COLD outside either - just if the engine was cold. It happened in winter, summer, whatever. I took it in and they verified this bulletin and performed procedure. They had already done a couple including one of the dealer salesman already so were aware. It covers all VIN in the covered years 2.5 natural through the fed emissions you don't even need to be inside your bumper to bumper. Like the bulletin says it is caused by "improper TCM control logic." It's not a user behavior problem or warmup issue at all. They acknowledged, they fixed it. It has now been 2 months and no problems or side effects at all. Every shift is smooth. Great car. On my service record it says it all.

Great news man. Mazda did a good job root causing the issue and releasing an update. Great having forums like this so owners can share bulletins so we know a fix is available. Can't exactly take the car in daily wondering!

 

I took my 23 CX-5 into my dealer yesterday for a TCM reprogramming per the TSB. No hassles, no issues, no problems, took about an hour, and best... no charge. I could tell a difference immediately on my drive home. The proof was this morning doing a cold test drive. The 2-3 flare/bang is gone. Not only is that issue resolved, so far all the shifts and transmixer behavior are very much improved. The shifting up and down in all gears is more firm, but smooth at the same time. The whole car feels more refined and upscale. So far I am very happy with the reprogramming. Again, only two days, we shall see. Thanks to 'campb292' for posting about the TSB. Tom

 

Glad to read this.




To bad we could not have used you as a test by having them do a simple pass-through of the ECU original programming? Unless you at some point get a ECU program like Versa Tuner that you download the complete ECU program and files we will likely not know for some time what changes (if any) were actually made?

 

I asked what was done, what files or code lines were changed. The answer I got was, "we just did a TCM reflash with the latest program that contains the fixes listed in the TSB". But it is apparent in my brief driving since the reflash, more changes were made than just addressing the 2-3 flare/bang issue. Thanks, Tom

 

Ya unfortunately a pass-through is more what you are describing rather than just a specific target area. It actually cost millions to do a complete ECU factory rewrite programing which I know Mazda did not do. So at best they did specific target area's for the transmission only. And it is too soon to see the ultimate results which will take a few thousand miles and at least 50 or more complete cycles.
So keeps us updated maybe in a few months?

I learned personally first hand with my own vehcle year ago about these manufactures ECU TSB, safety, emission etc. related recalls etc.
I went in for a emission related "reprograming" stated that it was for that only and nothing more. I left the dealership and thought WTF a notable power decrease? Went back to the dealership and they repeated the service and varied this time that it accepted the reprograming. Same result! So I drove home and immediately downloaded the ECU program top see what they had done. Afte spending a day or so studying files I saw the BS. My BMW was not suppose to be released for sale into the USA because it had none US programing specific for federal emission requirements. Even though the VIN showed federally approved for sales in USA and even for California emission standards requirements. Needless to say I stored that file and uploaded my program back into my ECU.... Back to power and throttle response and happy life!
I keep the file in case at some point I decide to ever sell that car and can place it back to the federally approved ECU programing.
